Title: Improvements in and in the manufacture of piston and like packing rings
IPC: F16J9/26
Filed: 1946-01-03
Abstract: 605,667. Making piston rings. BRITISH PISTON RING CO., Ltd., and TWIGGER, T. R. Jan. 3, 1946, No. 213. [Class 83 (ii)] In the manufacture of plated piston rings, the rings are plated before being split, and while they have an uninterrupted peripheral surface after which they are formed to the required shape by mechanical means, for example by hammering or rolling, or by heat forming, preferably carried out at between 400-550‹ C. in a non-oxidizing atmosphere. The unsplit rings are plated as they come from the finish turning or finish grinding operation and after plating may be given a further finishing as by honing or lapping. If desired, the rings may also be plated on their side faces, such side face plating being carried out by a separate operation at a suitable stage in the manufacture of the rings.

Title: Improvements in vehicle signalling apparatus
IPC: B60Q1/38
Filed: 1921-01-04
Abstract: 156,231. Swartwout, E. W. Aug. 23, 1916, [Convention date]. Road-traffic signals on vehicles.-In apparatus for indicating turning, stopping, or reversing and comprising a plurality of manually-operated means for indicating in advance of the movement of the steering-wheel the direction of intended travel, the manual setting means are rendered ineffectual by the movement of the steering wheel beyond a predetermined extent from its neutral position. The apparatus also includes interconnecting means for rendering only one of the manual means operative at a time, automatic means for indicating the course of travel after the steering-wheel has been turned, and means operative independently or conjointly with the above for indicating stopping or reversing. Two manually-operated plungers 2, 3 fitted at one side of the steering-wheel 5 make contacts 6, 7 and 10, 11 completing circuits through a battery 40 to light lamps 38, 47 respectively. These plungers are connected together by links 14, 15, Fig. 5, pivoted on pins 18, 19 and having similar concentric annular portions 16, 17 so arranged that when one of the plungers 2, 3 is depressed, the, act of depressing the second one causes the fingers 21, 23 to engage with the stops 22, 20 and restores the first to its neutral position. When the steering-wheel has been turned a predetermined amount, a radial finger 33 on the steering- column 32 makes contact with one of the arcs 34, 35 thus completing a second circuit through the appropriate lamp 38 or 47; and, also, and preferably slightly in retard of this contact being made, one of a. pair of cams on a support attached to the casing of the steering-column engages with the end 28 or 29 of the depressed plunger and restores it to the neutral position. The foot-brake 52, the emergency hand-brake 59 and the reversing-gear 67 are arranged to complete circuits through the same battery 40 to light lamps 56, 68 when operated to a predetermined extent. One or more pilot lamps, 74 .... 78 may be included in the circuits. The signals may be operated by mechanical means or by a combination of both electrical and mechanical means.

Fluid-actuated valves. - Apparatus tor supplying an anti-detonating agent to the cylinder of an internal-combustion engine when the compression therein exceeds a certain amount, comprises a movable member, such as a piston or a flexible diaphragm 30, which is subjected to the action of the vacuum existing in the induction pipe so that a valve 23 is opened by a spring 36, to admit the anti-detonating agent, when the vacuum is small owing to a full opening of the throttle. The valve 23 is shown as a conical lift valve engaging annular seats 24, 25, and also inclined seats formed on a central partition 27, and controls a passage 19 connected to a pipe 21 leading to the air intake of the carburettor 12.

Abstract: 546,598. Fuel injectors. AMERY, G. Jan. 17, 1941, No. 650. Addition to 443,124. (Class 7 (iii)] In a fuel-injection valve as described in the parent Specification, which is both opened and closed by the fuel pressure acting on opening and closing pistons, the spring which assists the closing of the injection valve is omitted. Fig. 1 shows the stem 49 of the injection valve connected to a closing-piston 48, to which fuel pressure is admitted at 41 bv a distributing valve 'in the manner described in the parent Specification. This fuel pressure also acts on another piston 47 which closes an obturating-plunger 32 over a passage 27 in a further plunger 23, 25. When injection is to commence the distributing valve cuts off the pressure at 41, and the fuel pressure admitted at 11 acts on the plunger 23, 25 to move it downwards into contact with a raised shoulder 30, after which this fuel pressure moves the plunger 32 downwards, and thus allows fuel to pass into the space beneath the plunger 25, and so by passages 59, 56 to the injection valve, which it opens. To close the injection valve, pressure is again admitted at 41, the remaining fuel pressure being relieved through the passages 59, 56, 33 to a chamber 29 open to atmosphere or to a drain ; or it may merely be relieved into a cavity at the upper end of the plunger 32, so that the fuel is not lost. The plunger 25 may be separate from the plunger 23, or may be omitted. Specification 501,632, is referred to.

Title: Improved fluxes and flux-coated electrodes for electric welding
IPC: B23K35/04
Filed: 1936-01-08
Abstract: A flux for electric welding, and particularly for coating welding electrodes of stainless steel, comprises a mixture of cryolite, felspar, talc and calcium carbonate with a binder. Suitable binders are formed by a soluble alkaline silicate such as sodium silicate, gum arabic, and the organic silicates known as silicon esters. Plastic clay may be added to render the paste self-lubricating for coating by extrusion, in which case the felspar content is proportionately diminished.  Suitable proportions by weight for the mixture are: cryolite, 50-60 per cent; felspar, 10-25 per cent; talc, 5-15 per cent; calcium carbonate, 5-15 per cent; plastic clay, 0-7 per cent, sufficient binder and reducing fluid being added to form a paste.  The electrode is preferably given a fibrous covering, advantageously a blue or white asbestos flyspin wrap with a small admixture of cotton.  A suitable composition by weight for a stainless steel electrode comprises:-chromium, 19-21 per cent; nickel, 8,5-9,5 per cent; silicon, 1,5-2,5 per cent; manganese, 0,4-0,6 per cent; iron, the remainder.  With certain steels slight additions may be made to the flux; for example with an electrode of similar composition to that above, but in which most of the silicon is replaced by titanium and possibly tungsten, about 5 per cent of titanium powder may be added to the flux.
